The text in info_str in creature_names should be empty if you are to see the default cursor when you point at your npc. Also subname needs to be empty if your npc does not have a sub name. When you created the npc manually, you where not allowed to leave these fields empty so you had to put something there. (maybe a space or some other symbol) Go back to creature_names and delete anything in these fields. Remember to always return and correct these fields after you add the npc manually. info_str contains the cursor data for this npc, you can play around with that using some of the provided strings in the wiki I linked here.
